# 配环境多用yarn，而npm不要用，这个包会不兼容。然后启动用npm start 打包用yarn build
# yarn build 失败，报错 每个ts，js都加上下面这个在开头
/* eslint-disable */This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.
The page will reload when you make changes.
You may also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can't go back!
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
You can learn more in the Create React App documentation.

该框架建议yarn和npm混用
我更推荐挂在github page上(✔)
或者可以用ngnix
# 启用和关闭这些服务
systemctl stop nginx
systemctl start nginx后端运行python flask程序进行收发
export FLASK_APP=/usr/pythoncode/backend.py #在任意目录下都可
flask run
flask run --host=0.0.0.0 #这将使您的服务器在外部 IP 上可用。但请注意，这样做可能会暴露您的服务器面临安全风险。在生产环境中，请确保使用适当的安全设置和防火墙配置。
nohup flask run --host=0.0.0.0 & #一直运行,用上秒的sudo kill来杀死这个进程购买的服务器建议用centOS(建议使用这个)
